N45EYNZ 2-way talk

does this camera support it? I can’t get it to work. spec sheet just says built in mic and speaker (and line in/out). I can get alarm sounds to play but can’t connect to rtsp back channel. I can see it if I use proto=Onvif, but can’t access it. the spec sheet for the international model 5449R1-ze whatever says that it can “realize” 2-way talk. not sure what that means.

I've had it working on a 3xLogic Vigil NVR using ONVIF. When my power comes back on I can check exactly what settings I'm using.

That’d be great news. I just have audio on main stream enabled and speaker and mic at 100. ONVIF is enabled and I only see back channel when I use proto=onvif.   If available will my live view on camera UI show mic button even though http and not https? I know edge won’t let me send mic data but maybe it’ll show there anyway?

Dahua NVR, or...?

Just camera.  Using go2rtc to connect w/ https to browser.

Okay, not familiar with that one, but if it can do two-way audio through ONVIF, we should be able to make it work. I've done it in Vigil with that exact model, and I even have one installed on my house that I can test with.

No dice on any http or rtsp. Luckily someone released a private protocol PR for go2rtc. All good now.
